Reliability

The range of sensor applications used to be limited in the past, but now it is expanding and diversifying. In line with this trend, the reliability specifications for our products are also changing.
Basic reliability tests such as heat resistance, cold resistance, moisture resistance, and thermal shock, along with PCT, HALT, HAST, and Boiling tests, are increasingly required for products. As a result, the reliability of products is becoming more important for quality assurance, with specific and detailed requirements for materials, structures, and usage ranges. The company possesses state-of-the-art facilities and conducts the following reliability tests to ensure product quality.
